Sir , any positive hopes on the above problem.
I tried the below. Go to apps - running - kill the bluetooth PBAP service.
Then pair with head unit. Then i see connected to JVC head unit in your application.
If i do not stop the stock PBAP process manually i do not see connected in your app.
But when it shows connected, the phonebook and call logs take almost 15 minutes to show up.
